EAGER: Developing Theoretical Foundation for Cooperative Communications with Network Coding

本项目的目标是研究网络编码对协作通信的影响，并为这一新兴领域奠定理论基础。在他们的初步结果中，PI发现，在目的节点的信号提取期间，使用模拟网络编码将不可避免地引入新的噪声。这种新的噪声将直接影响容量计算，导致协作通信中的容量变小。也就是说，使用网络编码可能并不总是有利于合作通信，这对一些研究人员不利？信仰。受这一结果的启发，PI计划在一般的多会话环境中系统地研究网络编码对协作通信的影响。智力优势包括探索和理解信号提取的各种方法以及信号提取过程中引入的潜在噪声。基于这一新知识，PI还计划重新探讨在协作通信中使用网络编码的一些重要问题，并提供新的和正确的理解。这样的理解不仅为进一步的研究提供了坚实的基础，而且具有变革的潜力，使现有的网络编码和协作通信理论更接近实践。该项目的更广泛影响包括开发跨学科教材和课程。在所有私家侦探中？根据他们在无线网络研究方面的经验，他们发现，无线通信方面的高级材料超出了学生在网络方面的典型教育。该项目的一个组成部分将是通过新的跨学科课程弥合网络和无线通信课程之间的差距。

The goal of this project is to investigate the impact of network coding on cooperative communications and to lay a theoretical foundation in this new and growing field. In their preliminary results, the PIs found that the use of analog network coding will inevitably introduce new noise during signal extraction at a destination node. Such new noise will directly affect capacity calculation and result in smaller capacity in cooperative communications. That is, the use of network coding may not always benefit cooperative communications, which is against some researchers? belief. Enlightened by this result, the PIs plan to systematically investigate the impact of network coding on cooperative communications in a general multi-session environment. The intellectual merit includes exploring and understanding various approaches in signal extraction and the potential noise introduced during the signal extraction process. Based on this new knowledge, the PIs also plan to re-visit a number of important problems that employ network coding in cooperative communications and offer new and correct understanding. Such understanding will not only offer a solid foundation for further research, but also has transformative potential to bring the existing network coding and cooperative communications theories one step closer to practice. The broader impact of this project includes the development of cross-disciplinary educational materials and courses. Throughout the PIs? experience with wireless networking research, they have found that advance materials in wireless communications are beyond the typical education for students in networking. An integral part of this project will be to bridge the gap between networking and wireless communications curricula via new cross-disciplinary courses.
